I have met many female fighters and actually concider a couple of the friends. The are all tough as nails. I am not going to pick one over the to other for the toughness question. I will however proudly say that I have been infatuated with Ginele Marquez since I first saw her in Nov. of 2004. I have since met her and she has warned me to say away from Washington or she will either kick my ass or file for a restraining order. :-)
I would also bet my annual income that no female in any combat sport can drop JägerBombs faster. In my long life, there are few things that I have witnessed as amazing and her downing those things.
